I respectfully don't agree with some of your points. Many people have been cured, and many people obviously haven't, so clear it is down to the individual. Maybe other factors are involved, like the person's effort, genetics, or misdiagnosis of the problem. Speech therapy isn't for everyone, and there are many people who haven't improved from it, while many others have. Well I guess in a way we are both agreeing to that. Everyone is entitled to their own opinion, as I have mine and you yours.
